Nomenclature & Type numbering

Standard B-style assemblies

SCIONIX scintillation detectors are characterized by a type number in which most of the properties of the instrument can be found. However, there remain features that are not “captured” in the type number (e.g. special geometries or electronic features) since there is an large number of ways a scintillation detector can be constructed. In this case the suffix -Xxx is added to the type number which refers to “special”. Note that for some of the nine features below, more than one option may apply.

In case of phoswiches, the height of the primary crystal precedes the letters PH followed by the height of the secondary (guard) crystal.

6. Size and Quantity of the light detector

When the readout is with a photomultiplier (PMT) the number here is the diameter of the PMT in inches. In case of more than one PMT, the number is indicated in brackets after the diameter; e.g. / 3(3) indicates three 76 mm PMTs

When the readout is with a silicon photomultiplier (SiPm), the type number shows here “SiP“ with in brackets the number of SiPm modules.

In case of photodiode readout, the size of the photodiode is indicated in mm.
